The prevalence of schizophrenia is reported to be as high as 1.5 % worlwide, having an annual incidence of 5 per 10, 000 people according to the American Psychiatric Association. Schizophrenia usually becomes manifest in early adulthood, between the age of 16 and 25. People with shizophrenia experience positive (such as hallucinations and delusions), negative (i.e. apathy, lack of emotion, poor or nonexistant social functioning) and cognitive (disorganized thoughts, difficulty concentrating and/or following instructions, difficulty completing tasks, memory problems) symptoms. These symptoms lead to social and occupational dysfunction, which inevitably has a profound effect on the affected person's family and the person's place in the wider society.
